<P>PROBLEM TO BE SOLVED: To provide a torque transmission mechanism usable in a wider temperature region than conventional one. <P>SOLUTION: The torque transmission mechanism 10 comprises a rotating shaft 11, and a rotor 12 having a shaft hole 14 into which the rotating shaft 11 is pressed, wherein a shaft hole fastening part S1 is formed to fasten the rotor 12 and the rotating shaft 11 to each other with he rotating shaft 11 pressed into the shaft hole 14 so that torque is transmitted between the rotating shaft 11 and the rotor 12 through the shaft hole fastening part S1. A cylinder body is pressed and fastened into the outer peripheral face of the rotating shaft 11. The cylinder body has an inner diameter face 28 concentric with an axis P of the rotating shaft 11, and the rotor 12 has an outer diameter face 21 concentric with the axis P of the rotating shaft 11. The inner diameter face 28 is pressed into the outer diameter face 21 to form a cylinder fastening part S3 which fastens the rotor 12 and the cylinder body to each other. The cylinder body is formed of a material having a lower thermal expansion coefficient than that for the rotor 12. <P>COPYRIGHT: (C)2010,JPO&INPIT |
